electric charge-QUANTIZED AND CONSERVED CHARGE


HEY GUYS:
I HAVE ONE SPECIAL WORD THAT MAYBE YOU HAVE ALWAYS USED IT WITHOUT EXACTLY KNOW THE MEANING OF IT..

Ever heard the word 
QUANTUM? QUANTIZED? QUANTISATION?
I bet you have .. but do you know the meaning?
Quantized means that you are referring a group of particles as one specific volume..
For example ; take a deep breath now. Do you know how many of oxygen you are breathing in?? what about carbon dioxide? And other particles such as dust?
So, we have to quantized and ASSUME the oxygen,CO2 and other have specific volumefor ONE single particles. Get it?
Straight to the point,when you heard that charge is quantized it means that they can have only discrete values rather any values. Using the discrete value, it is possible to calculate the particle that has no charge at all or +122e or -3e. However, it is completely unlogical if you are saying that you can find the value of 10.57 e!
it means electric charge cant have any value .
it must be a multiple of 1.6*10^19
as
q = n e
where e = charge on an electron
n = number of electron (1,2,3,4 ..........)
now you do understand right?
J barakallah
Then HOW ABOUT CONSERVATION OF CHARGE??
DOES THAT PHRASE EVEN EXIST AND POSSIBLE FOR CHARGE?
DOES CHARGE CAN BE CONSERVE? HOW?
The net charge of an isolated system remains constant. The only way to change the net charge of a system is to bring in charge from elsewhere, or remove charge from the system.
Charge can be created and destroyed, but only in positive-negative pairs.


Example

Two identical metal spheres are charged. Sphere A has a net charge of +7Q. Sphere B has a net charge of -3Q. The spheres are brought together, allowed to touch, and then separated. What is the net charge on each sphere now?
1.     Each sphere has a net charge of +4Q
2.     Each sphere has a net charge of +2Q
3.     Sphere A has +4Q, Sphere B has no net charge
4.     Sphere A has +7Q, Sphere B has -3Q
When the spheres are touched the net +4Q charge will spread out evenly over the two spheres. Each sphere will have a net charge of +2Q.
SIMPLE EXAMPLE.! J
